【Abstract】 The thermal stability of N 2 on Mo(100) surface was studied by Auger electron spectroscopy (AES), low energy electron diffraction (LEED) and thermal desorption spectroscopy (TDS). It was found that when the Mo(100) surface was exposed to 1?500 L of N 2 and then heated up to 1?100 K, a good model Mo(100) c(2×2)N structure could be obtained. Heated to 1?300 K, the structure began to be destroyed and the c(2×2) LEED pattern disappeared. The N atoms recombined into molecules which desorbed from the surface at 1?300 K.更多还原
